HOSE-NOZZLE.

Specification of Letters Patent.

Application filed October 12, 1908. Serial No. 457,265.

zen of the United States, and a resident of- Chicago, county of Cook,and State of Illin'ois, have invented certain new and usefulImprovements in Hose-Nozzles,.of which I do declare the following to bea full, clear, and exact description, reference being had to theaccompanying drawing, forming part of this specification.

The present invention has relation more particularly to that class ofhose nozzles in which provision is made whereby the water may be causedto issue from the nozzle, either in a solid stream or more or less inthe form of spray.

The obj ect of this invention is to simplify and cheapen theconstruction of such type of hose nozzle, and the invention consists inthe features of improvement hereinafter described, illustrated in theaccompanying drawing and particularly pointed out in the claims at theend of this specification.

Figure 1 is a view in elevation showing a hose nozzle embodying myinvention, thenozzle being illustratedas applied to the end of a sectionof hose. Fig. 2 is a View in central longitudinal section through thehose nozzle with the parts in position for throwing a full stream ofwater. Fig. 3 is a view in central longitudinal section through thenozzle when its parts are turned to cause the water to issue in the formof spray. Fig. 4 is a detail view in horizontal section through theupper portion of the nozzle on line 4 4 of Fig. 5. Fig. 5 is afractional view in longitudinal section through the base portion of theupper part of the nozzle. Fig. 6 is a view in elevation of the innermember of the improved nozzle. Fig. 7 is a sectional view similar toFig. 5 but taken on another plane.

1 designates the section of hose to which the nozzle is attached, theend of the hose being shown as provided with a coupling 2 that will havea screw threaded portion adapted to enter and engage the correspondinglyscrew threaded portion 3- of the expanded part 4 of the inner member ofmy improved nozzle. The inner member of the nozzle has a hollowchambered portion 5, beneath the top 6 in the side wall of which areformed openings 7 through which the water will issue as it is deliveredto the chambered portion 5. Beneath the openings 7 an annular flange 8is formed on the reduced portion 5 of the inner member of the nozzle andupon this annular shoulder 8 will set ;an inwardly projecting annularflange 9 that is formed upon the interior of the outer member 10 of thenozzle. The outer member 10 of the nozzle has a part 11 adapted to setover the flange 8, and when this part 11 has been placed in position, asshown in Figs. 2

and 3, the lower edge portion of this part 11 will be bent inwardly, asshown, inorder to retain the suitable packing 12 between the flange 8and the lower edge of the part 11, and prevent the escape of water atsuch point.

The outer member 10 of the nozzle is chambered and is shown as havingits end flaring and as having a transverse Wall 14 provided witha'discharge port 15- for the passage of water 'therethrough. Upon theinterior of the outer member 10, and above its flange 9 are formed tworibs or offsets 16 and 17. There are two ribs 16 and these are arrangeddiametrically opposite each other, and similarly there are two ribs 17at opposite points of the member 10 of the noz- -zle. By reference more,particularly to Fig.

5 it will be seen that the ribs 16 and 17 cooperate to form an inclinedchannel 18, the purpose of this channel being to impart a swirling orrotary motion to the stream of water as it passes through the chamberedportion 10 of the nozzle. As shown, the inner end of each of thechannels 18 is straight and by reference to Fig. 3 of the drawing itwill be seen that when the upper or outer member 10 of the nozzle isturned by hand, so that the discharge ports or holes 7 are opposite thestraight portions of the channels 18, water will pass through the ports7 and into the channels 18 and will thus have a rotary or swirlingmotion imparted thereto. This will tend to break up the stream of waterand as the water issues through the restricted discharge port 15 it willpass from the nozzle in the form of spray.

By reference to Fig. 7 it will be seen that between the straight face ofthe rib 16 and the straight face of the adjacent rib 17 there is formeda straight channel 20. When the outer portion 10 of the nozzle is turnedso as to bring the ports 7 op osite the straight channels 20, the waterwill pass Patented Jan. 9, 1912. r

or swirling motion imparted thereto. Consequently, with the parts in therelative poand the outer or upper member, and each of these parts ismade as a slngle casting so that when the parts are assembled it is onlynecessary to place one upon the other, insert the packing 12 and crimpor bend inward the lower portion 11 of the upper member;

In using the nozzle the operator will turn the upper member 10 With hishand so as to bring the parts into either the position seen in Fig. 2 tothrow an unbroken stream, or into the position seen in Fig. 3 to throw astream more or less in the, form of spray.

It is manifest that the precise details above described may be variedwithout departing from the scope of the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A hose nozzle of the character described comprising an inner memberhaving an upper portion provided with one or more side ports, and anouter member revolubly mounted upon said inner member and pro-- videdwith one or more inclined passages adapted to be brought opposite saidports of the inner member.

2. A hose nozzle of the character described comprising an inner memberhaving adapted to be brought opposite said ports of the inner member.

4. A hose nozzle of the character described comprising an inner memberprovided with a peripheral flange and a part extending above said flangehavin one or more lateral ports, an outer mem er provided with aninterior flange to engage the peripheral flange of said inner member andhaving a chamber of considerably larger diameter than the inner member,said outer member having upon its interior inclined and straightchannels and having a restricted discharge port at its end.
